Cell surface antigen profile in ChDPSCs. A total of thirteen cell surface antigens were used to characterize the expression profile of ChDPSCs and hBMSCs. Both ChDPSCs and hBMSCs share identical expression profiles on common cell surface antigens. They were all negative for hematopoietic cell surface markers: CD14, CD34, and CD45; yet identical on cell surface markers shared with BMSCs (CD29, CD44, CD59, CD73, CD90, CD105, CD150 and CD166). Furthermore, all cell lines were negative for CD18 and CD24. Blue line: isotype control. Red line: marker of interest.
